<h2 id="1-1-m3u8文件简介"><a href="#1-1-m3u8文件简介" class="headerlink" title="1.1 m3u8文件简介"></a>1.1 m3u8文件简介</h2><p> 现在很多视频网站采用流媒体技术进行播放视频，一种常见的方案是m3u8文件+ts文件。m3u8是苹果公司推出一种视频播放标准，是m3u的一种，不过编码方式是utf-8，是一种文件检索格式，将视频切割成一小段一小段的ts格式的视频文件，然后存在服务器中（现在为了减少I/O访问次数，一般存在服务器的内存中），通过m3u8解析出来路径，然后去请求。</p>
<h2 id="1-2-Selenium简介"><a href="#1-2-Selenium简介" class="headerlink" title="1.2 Selenium简介"></a>1.2 Selenium简介</h2><p>Selenium是一个Web的自动化测试工具，最初是为网站自动化测试而开发的，Selenium 可以直接运行在浏览器上，它支持所有主流的浏览器（包括PhantomJS这些无界面的浏览器（2018年开发者说暂停开发，chromedriver也可以实现同样的功能）），可以接收指令，让浏览器自动加载页面，获取需要的数据，甚至页面截屏。</p>

<h1 id="2-分析及实现"><a href="#2-分析及实现" class="headerlink" title="2 分析及实现"></a>2 分析及实现</h1><h2 id="2-1-分析"><a href="#2-1-分析" class="headerlink" title="2.1 分析"></a>2.1 分析</h2><p>本文以影片<a target="_blank" rel="noopener" href="http://www.kanjp.com/play/157418-1-1.html">《金刚川》</a>为例，前期通过查看网页源代码发现无法查找到视频源地址，通过检查元素，可以查看到一个m3u8地址。但该部分代码采用动态加载，因此采用Selenium库进行请求，采用正则表达式将m3u8地址取出。</p>
<img src="/posts/fdc2c90f/Snipaste_2021-02-27_17-07-34.png" alt="" style="zoom:100%;">

<p>用浏览器访问该地址，发现是视频播放页，进入开发者模式，并切换到Network选项卡，发现请求该地址后，请求了两个index.m3u8链接。</p>
<img src="/posts/fdc2c90f/Snipaste_2021-02-27_17-12-17.png" alt="" style="zoom:100%;">

<p>查看第一个index.m3u8链接的请求头，发现请求url为之前正则匹配出来的m3u8地址的后半部分，因此可以修改正则表达式，直接匹配出该地址。</p>
<img src="/posts/fdc2c90f/Snipaste_2021-02-27_17-39-35.png" alt="" style="zoom:100%;">

<p>该m3u8文件内容为：</p>
<img src="/posts/fdc2c90f/Snipaste_2021-02-27_17-40-24.png" alt="" style="zoom:100%;">

<p>查看第二个index.m3u8链接的请求头，发现请求url为第一个m3u8文件的请求url将index.m3u8换成了第一个m3u8文件内容的第三行</p>
<img src="/posts/fdc2c90f/Snipaste_2021-02-27_17-40-48.png" alt="" style="zoom:100%;">

<p>而该m3u8文件内容即为ts流列表：</p>
<img src="/posts/fdc2c90f/Snipaste_2021-02-27_17-41-26.png" alt="" style="zoom:100%;">

<p>点击第一个ts流并查看其请求url，可以发现为第二个m3u8文件链接将index.m3u8换成了ts流的编号。</p>
<img src="/posts/fdc2c90f/Snipaste_2021-02-27_17-58-26.png" alt="" style="zoom:100%;">

<p>至此整个分析完毕，整个抓取思路为：<br>Selenium库请求视频播放页–&gt;正则匹配出第一个m3u8文件地址并请求该地址获得文件内容–&gt;将第一个m3u8文件链接与其文件第三行内容拼接得到第二个m3u8文件地址并请求该地址获得文件内容–&gt;遍历第二个m3u8文件提取出所有的ts流编号并与第二个m3u8文件地址拼成正确的ts流地址–&gt;请求ts流并保存文件。</p>
